Your getting the error (1) because you have "Set Hosts to Cydia on Exit" checked in the advanced tab in TinyUmbrella to restore it to 5.0.1 you have to uncheck it.

You won't be able to unlock it via ultrasn0w now since you updated the baseband when you updated to 5.0 and a downgrade will not downgrade the baseband just the firmware.
